Hemaokang Steel (Shandong) Co., Ltd. is proud to present our high-quality SGLCC SGLC440 Galvanized Steel Coil, designed specifically for structural applications. With a thickness range of 1.0 to 3.0 mm and a hot-dip galvanized coating of 275 g/m², this coil delivers exceptional corrosion resistance and mechanical strength. Backed by our ISO9001-certified production facility and an annual export value exceeding US$50 million, we ensure that every coil meets the rigorous demands of global construction and industrial projects.
Our galvanized steel coil is manufactured using advanced hot-dip galvanizing lines, guaranteeing uniform zinc adhesion and a consistent surface finish. The SGLC440 structural grade ensures reliable performance under load, making it ideal for roofing, wall panels, purlins, and other load-bearing components. Below, we break down the key features and specifications that set our product apart.
Key Features & Benefits
- Superior Corrosion Resistance: The 275 g/m² zinc coating (both sides) provides long-lasting protection against rust and environmental exposure, even in humid or coastal conditions.
- Structural Grade Strength: SGLC440 offers a minimum yield strength of 440 MPa, ensuring excellent load-bearing capacity for structural applications.
- Excellent Formability: The hot-dip galvanized layer remains ductile, allowing for bending, stamping, and roll-forming without cracking or peeling.
- Uniform Coating Thickness: Advanced process control ensures a consistent zinc layer across the entire coil surface, minimizing waste and improving fabrication efficiency.
- Wide Thickness Range: Available from 1.0 mm to 3.0 mm, catering to diverse structural requirements from light framing to heavy-duty supports.
- Customizable Width: We can supply coils in widths from 600 mm to 1500 mm, with options for slitting or cutting to length.
- Eco-Friendly Production: Our manufacturing process complies with environmental standards, using recyclable materials and energy-efficient technologies.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between SGLCC and SGLC440?
A: SGLCC is our product model code, while SGLC440 refers to the structural steel grade (minimum yield strength 440 MPa). They are used interchangeably in our catalog. -
Q: Can you supply coils with a higher zinc coating weight than 275 g/m²?
A: Yes, we can provide zinc weights from Z100 to Z350 (or even higher) upon request. Please specify your requirement. -
Q: What is the typical lead time for this product?
A: For standard specifications, lead time is 15–20 working days after confirmation. Custom orders may require 25–30 days depending on quantity. -
Q: Do you offer samples before bulk order?
A: Yes, we can provide small samples (e.g., 1m x 1m sheet) for quality evaluation. Sample cost is negotiable and can be deducted from the final order. -
Q: Is the coil suitable for outdoor structural use?
A: Absolutely. The hot-dip galvanized coating with 275 g/m² is designed for long-term outdoor exposure, providing excellent resistance to corrosion and weather. -
Q: What certifications do you hold?
A: Our factory is ISO9001:2015 certified. We can also provide a mill test certificate (MTC) for each shipment upon request. -
Q: How do you package the coils for export?
A: Coils are packed with anti-rust paper, plastic wrap, steel strapping, and wooden pallets or steel frames for sea freight. Custom packaging is available. -
Q: Can you supply cut-to-length sheets instead of coils?
A: Yes, we offer cut-to-length services (e.g., 1.0m x 2.0m sheets) and slitting as per your dimensions. Additional charges may apply.
